Abstract:
We consider the multiplicity of stellar systems with (combined)
magnitude brighter than 6.00 in Hipparcos magnitudes. We identify 4559
such bright systems (including the Sun), and the frequencies of
multiplicities 1, 2, ... , 7 are found to be 2718, 1437, 285, 86, 20,
11 and 2. We discuss the uncertainties, which are substantial. We also
consider the distributions of periods of orbits and suborbits. We note
that for even more restricted set of 478 systems with VH≤4.00 , the
proportions of higher multiples up to sextuple are progressively
larger (213, 179, 54, 19, 8, 5), suggesting substantial incompleteness
in even the reasonably well studied larger sample.
